You CAN do it with a fridge top freezer (the ones on the bottom stink) or a side by side LOL
Just do meals that can be stored flat. Do them in gallon zip top bags, freeze them flat, then stack them like record albums in your freezer. You'd be amazed at how many you can fit in to save yourself some time down the road. Even if you don't do a whole month at a time, you can do chunks at a time and really help yourself out!

This was the site that set me off on my path.
That and a bumper crop of apples. I had to get a
freezer after we had too much to deal with.
I got my freezer off craigslist.
